Select the letter-cluster from among the given options that can replace the question mark (?) in the following series.
WXYZ, YZWX, ABUV, CDST, ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. EFQR.
The logic used here is:
W + 2 = Y, X + 2 = Z, Y - 2 = W, Z - 2 = X
Y + 2 = A, Z + 2 = B, W - 2 = U, X - 2 = V
A + 2 = C, B + 2 = D, U - 2 = S, V - 2 = T
